Table 2. Detailed ED visits characteristics for the 1-lead ECG group and the standard care group, per 100 patients.

The first row is the primary outcome (total ED visits). First column is the absolute number of visits in the first year after PVI, and the second column is the number of visits per 100 patients. The first 3 rows include p-value for comparison (Marginal mean model—Wald test, see methods section).
